7. Maintenance

To ensure the longevity and optimal performance of your Rock Pi 4B, consider the following maintenance tips:

• Keep it Cool: Ensure adequate ventilation, especially when running demanding applications. The included heatsink should be installed to dissipate heat from the SoC.
• Cleanliness: Keep the board free from dust and debris. Use compressed air or a soft brush for cleaning.
• Power Supply: Always use a stable and appropriate power supply (5V-3A USB Type-C PD) to prevent damage.
• Static Electricity: Handle the board with care to avoid electrostatic discharge (ESD), which can damage sensitive components.

8. Troubleshooting

If you encounter any issues with your Rock Pi 4B, consider the following general troubleshooting steps:

• No Power: Verify the power supply is correctly connected and providing the correct voltage and current. Ensure the USB-C cable is functional.
• No Display: Check HDMI cable connections and ensure your display is set to the correct input. Test with a different display or cable if possible.
• Operating System Issues: Re-flash your eMMC module or SD card with a fresh OS image. Ensure the image is compatible with the Rock Pi 4B.
• Peripheral Not Detected: Check USB connections. For the USB 3.0 OTG port, ensure the host/device switch is in the correct position.
• Overheating: Confirm the heatsink is properly installed. Reduce workload or improve ventilation if the board feels excessively hot.
